Descriptionhttp://www.DataSheet4U.net/
The IL3685 is a galvanically isolated, high-speed differential bus
transceiver, designed for bidirectional data communication on
balanced transmission lines. The device uses NVE’s patented*
IsoLoop spintronic Giant Magnetoresistance (GMR) technology.
The part is available in an ultraminiature 0.15" 16-pin SOIC package
or a 0.3"-wide package for full 8 millimeter creepage.
The IL3685 is fully PROFIBUS compliant, including the rigorous
PROFIBUS differential output voltage specifications.
A unique ceramic/polymer composite barrier provides excellent
isolation and virtually unlimited barrier life.
The device is compatible with 3 V as well as 5 V input supplies,
allowing interface to standard microcontrollers without additional
level shifting.
Current limiting and thermal shutdown features protect against
output short circuits and bus contention that may cause excessive
power dissipation. Receiver inputs feature a “fail-safe if open”
design, ensuring a logic high R-output if A/B are floating.
IsoLoop® is a registered trademark of NVE Corporation.
*U.S. Patent number 5,831,426; 6,300,617 and others.

Notes (apply to both driver and receiver sections):
1. All voltages are with respect to network ground except differential I/O bus voltages.
2. Differential input/output voltage is measured at the noninverting terminal A with respect to the inverting terminal B.
3. Skew limit is the maximum propagation delay difference between any two devices at 25°C.
4. The power-off measurement in ANSI Standard EIA/TIA-422-B applies to disabled outputs only and is not applied to combined inputs and
outputs.
http://www.DataSheet4U.net/
5. All typical values are at VDD1,VDD2 = 5 V or VDD1= 3.3 V and TA = 25°C.
6. −7 V < VCM < 12 V; 4.5 V < VDD < 5.5 V.
7. Δ|VOD| and Δ|VOC| are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from one logic state to
the other.
8. This applies for both power on and power off, refer to ANSI standard RS-485 for exact condition. The EIA/TIA-422-B limit does not apply
for a combined driver and receiver terminal.
9. Includes 10 ns read enable time. Maximum propagation delay is 25 ns after read assertion.
10. Pulse skew is defined as |tPLH – tPHL| of each channel.
11. Absolute Maximum specifications mean the device will not be damaged if operated under these conditions. It does not guarantee
performance.
12. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 6.
13. External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin” (see diagram on p. 6).
